(Occupational Safety and Health Act).
2. This unit must be properly grounded.
3. Always disconnect the power supply prior to
servicing the fan, motor or junction box.
4. Do not bend or kink the power wires. Protect
from sharp edges, oil, grease, hot surfaces,
chemicals or other objects.
5. Do not install where the room air temperature
will exceed 40˚C (104˚F).
6. Do not install over a tub or mount in a shower
stall enclosure.

10. Use this unit in the manner intended by the
manufacturer.
11. If you have any questions, please call the
manufacturer.
12. Installation work must be carried out by a
qualified person(s) in accordance with all local
and safety codes including the rules for fire-
rated construction. For use in non-fire rated
installations only.
13. Sufficient air supply is required for proper
combustion and the exhaustion of gases through
the chimney (flue) of fuel burning equipment
to prevent back-drafting. See the standards
of NFPA (National Fire Protection Association)
and ASHRAE (American Society for Heating
Refrigeration and Air Conditioning Engineers)
and the local building code authorities.
14. Exercise care to not damage existing wiring
when cutting or drilling into walls or ceilings.
15. Fans should always be vented to the exterior
and in compliance with local codes.
16. Do not use this fan with any solid state control
device such as a dimmer switch. Solid-state
controls may cause harmonic distortion, which
can cause a motor humming noise.
17. Prior to service or cleaning this unit, shut off
power supply at the panel and lock to prevent
the power from being turned on. If the panel
cannot be locked, clearly mark the panel with
a warning tag to prevent the power from being
turned on.
18. Do not install in a ceiling with insulation greater
than R40. (This is required for installations in
Canada only.)
19. Duct work should be installed in a straight line
with minimal bends.
20. Duct work size must be a minimum of the
discharge and should not be reduced. Reducing
the duct size can increase fan noise.
21. This ventilating bath fan is intended for
residential use only in 1-2 family dwellings.
22. Never place a switch where it can be reached
from a tub or shower.
23. Make sure that the electric service supply
voltage is AC 120 V, 60 Hz.
24. Always disconnect the power source before
working on or near the unit.
25. This unit is designed and tested to be a
supplemental heater for use with a timer or a
switch. It is not intended to be used as a primary
source of heat, or controlled by a thermostat.
26. To avoid motor bearing damage and noisy and/
or unbalanced impellers, keep drywall spray,
construction dust, etc., off power unit.
27. Provide a separate 15 AMP circuit.
28. This product is designed for ceiling installation
only. Do not mount this product in a wall.
29. Install in ceiling only, at least 6 in. from any wall.

floor.
32. Do not install the unit where ducts are
confugured as shown in Fig. A.

Duct Tape, Phillips Head Screwdriver, Utility Knife
Helpful Tools (not included): Electric Drill, Drill Bits
WARNING: Turn off electricity at breaker box
before beginning installation.

interfere with installation work.
Check area above installation location to be sure
that wiring can run to the planned location and
that duct work can be run. Make sure the area is
sufficient for proper ventilation.
You may need the help of a second person to
install this fan: one person on the attic side and
one on the room side.
Note: Installations may vary depending on how the
previous bath fan was installed. Supplies necessary
for the installation of your bath fan are not all
included.
However, most are available at your local home
improvement or hardware store.
Proper insulation around the fan to minimize
building heat loss and gain.
The fan will operate most efficiently when
located where the shortest possible duct run and
minimum number of elbows will be needed.
Use a roof cap or wall cap that has a built-in
damper to reduce backdrafts.
External timer/dimmer switch can be used.
